If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment.
Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year.
However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey.
Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate(授粉) the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects!
While it is true that some species of insects harm or annoy us,you should not automatically reach for the bug spray when you come across an insect. You may be destroying one of the hundreds of thousands of insects that provides many benefits to human beings.

When the sand began kicking up and hitting our faces, I started to worry that maybe we had made a mistake.
That afternoon, my dad had stood on the deck (露台) of our home and laughed as our neighbors packed up their cars and headed inland. They left to spend the night in motels or at friends’ homes that were out of range of approaching summer storm.
Challenging the weather that threatened to damping our spirits, we lit a fire on the beach. Dad told jokes and we had a good time. When it was 6:30 p.m., all laughter disappeared. Our eyes were drawn to the sky. A tornado (龙卷风) was headed straight for us! In a flash, we were all on our feet. The wind started screaming and now we were running to the cottage. My mom stopped next to the front door. “Where can we go?” She shouted at my dad.
Most cottages on this part of Lake Michigan had been built without basements. Ours was no exception. The huge windows and the cottage itself wouldn’t offer safety from high wind.
“Follow me!” my dad yelled. We crawled (爬) beneath the deck, pressing ourselves against the foundation of the cottage. Between the deck supports, we watched the approaching storm in silent terror.
My dad shouted, “Hold on!” and something else I couldn’t hear over the screaming wind. I think he was praying. By the time it reached our cottage, it was nothing more than a strong wind. The rest of the storm lasted for an hour and then simply blew away.
“Next time, we’ll stay inland at Grandma’s. Okay?” my dad said.

C.Crawling on the ground. D.Running away at once.
3.Where did the family stay in the storm?
A.Under a deck. B.In a basement.
C.Inside the car. D.Behind a door.
4.What can be the best title for the text?
A.Life on the beach B.An Unusual Cottage
C.Surviving a Storm D.My Admirable Family
Still seeking a destination for your weekend break? There are some places which are probably a mere wall away from your college.
King’s Art Centre
A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.
You could attend a class teaching you how to ‘learn from the masters’ or get more creative with paint–free of charge.
The Centre also runs two life drawing classes for which there is a small fee.
The Botanic Garden
The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.
The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.
Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.
The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid’ is regularly seen lying in the heat of the warm sun.
Byron’s Pool
Many stories surround Lord Byron’s time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of “mess and drunkenness”. However, it seems as though Byron did manage to pass the time pleasantly enough. I’m not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village.
It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron’s Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don’t trust me, then perhaps you’ll take it from Virginia Woolf, a famous writer,—over a century after Byron, she reportedly took a trip to swim in the same pool.
1.The main idea of the passage is ________.
A.interesting stories of Lord Byron
B.an approach to becoming creative in art
C.the colorful life in the countryside
D.some places for weekend break
2.If you are a wildlife enthusiast, you’d better go to ________.
A.Byron’s Pool B.the Botanic Garden
C.King’s Art Centre D.Cambridgeshire
3.According to the passage, the following statements are wrong except ________.
A.there is a small charge for attending the masters’ class
B.Byron liked swimming naked in the lake
C.Byron seemed to like keeping pet bears
D.Hissing Sid and Flytrap are impressive animals
4.The author’s purpose in mentioning Virginia Woolf is to show ________.
A.she was a famous writer
B.she was keen on swimming
C.she was Byron’s admirer
D.Byron’s Pool is a pleasant place

Dear Peter,
I'm glad to hear from you. Thank you very much for inviting me to America in this summer. I'd like to accept your warm invitation, and I'm sorry that I can't go to your hometown and visit you.
I refuse your invitation just due to the following reason. First of all, it cost a lot to travel abroad, which will add an extra burden to my family. Beside, I plan to do part-time job in the summer vacation. I can not only earn some money to cover my expenses but improving my social skills. For the reasons mentioning above, I believe you can understand how I can't accept your invitation. I hope this won't affect our friendship from the bottom of your heart.
Yours,
Li Hua
